"lhisinvention relates to a dooi' device for railway cars and has among its objects toV provide a simple form of door closing and supporting mechanism. Another objectis to provide al door su )porting device wherein the door 'may be lifted by hand to a temporary position, and be retained in this temporary position by means of a portion of' the device, from) Whiclntemporary posiv be /forcibly close( by moving the supporting mechanism toits final position, the movement of the supporting mechanism causing the closing movement of the door. Another object is to provide, with a door, aswinging door hook which when supporting the door at the final closet osition, will be retainedpin that position" y interlocking of the supporting surfaces. Another object is to provide, with a door, a closing and securing device which may be effectively operated without the aid of special tools or attachments other than any available implement with which a'blow may -be struck, and further to provide on the supporting device a definite and `satisfactoryl lace on which the blows from the externa implemen-t'may be applied to force the supportiiigmember into final engagement with the door. l 1

Another object is to vprovide with a door, a member attached to thel door and arranged for co-operation .with a, swinging door supporting hook in such-manner that the engaging surfaces 'of the door member and the su porting ledge of the hook will,

ook is forced to its final osition, causev the door to be forcibly c osed and secured in the said closed osit1on,fbut

'so arranged that the interlocking surfaces securing the hook in the final position will noty he subject to wear from the Ic osin action or from forcing the hook to 1 fina position. I

W ith these and other objects 1n view, the invention consists of the formation, combination and'arrangement of parts as will be herein described and particularly claimed. lin the accompanying drawings, which i922. serial adminis.-

'show a preferred formof the' invention Figure 1 is a fragmentary side elevationa view, showing a portion of a car body equipped with doorsv and a supporting mechanism therefor embodying the principles-of the' present invention. lin this figure the door at the right side is shown as fully closed and the one at the left is shown as supported in a temporary and partly closed position. j

Figure 2 isa transverse verticalsection of the same, this view being taken approximately on the'line 2-2 of Figure l.

'Figure 3 is a view of/ a portion of the back of one of the door-supporting hooks, this View being taken substantially on the line `3 3 of Figurey 1. Figure 1 is a fragmentary sectional view through one'of the hooks, the section being taken on the line 4-4 of Figure 1. Figure 5 is a diagrammatical view .outlining the co-operating.

contours of the supporting ledge of a doorsupporting hook and of the hook Seat on the door. v *y Referring to these drawings, the side of the car is indicated by the numeral 1, and a fragment of the fioor of the car is shown at 2. A door 3 is hinged in the floor of the car by meansof co-operating body and door hinges 4 and 5, a hinge pintle being indicated at. The door in the present embodii'nent is shown as arranged transversely of the car. There is also shown a fragment of a similar door 7 ,'which, with the door 3,

may constitute a pair of symmetrical doors. Extending alonov the free edges of these doors are stiffening members of angular section indicated by 8 and 9. The ends of these stiffening members extend outward beyond the edges of the doors where'the,

constitute arms for (1o-operation wit swinging door-su porting members, such as the hooks 10. T ese angular members may be supplied with filler vpieces or hook seats such as 11, an embodiment of which wilf shortly be described; @ne of the hooks 10 is provided for each side of the door, and these are pivoted to the side ofthe car body by means of pintles l2. lA bracket 13 overs lies the outer faces of the hooks ,and the pintles 12 extend through' this bracket and through the side 1 of the car. Cotter pins such as 14 may be used to secure the pintles 12 against, loss. Additional securing means such as the rivets-15 may be provided for the bracket 13. Cams 16 of the customary ill@ type may be provided to hold the hooks in engagement with the door arms 8 and 9, these being shown as pivoted between the car side and the bracket 13 by means of the rivets 17. n addition, certain securing features are embodied in the hooks 10 and filler pieces 11 by arranging for interlocking o the interengaging surfaces of these parts. rlhis will be hereinafter described.

VPreferably each of the door supporting hooks 10 is provided with a supporting ledge 18, the contour of which is eccentrically inclined so that successive positions along the supporting ledge,beginning at the point of the ledge and progressing towards the root thereof, are successivelyv at decreasing distances from the pivot point of the hook. This causes a lifting motion to be imparted to the door when the hook is forced into engagement therewith.A

The point of the supporting ledge of the hook is preferably provided with a transverse coirugation, such as 19, thereby forining in effect 'a knob 20 at the extreme point of the supporting surface of the hook. Preferably the upper limit of the knob 20 is on line with, or at least not above, the,gen eral normal contour of the supporting ledges, an extension of this contour being indicated for reference purposes by the dotted line 21.

The general contour of the hook-engaging face 22 of the filler piece 11 is arranged to conform `to the contour of the supporting ledge when the hook is in full and final engagement with the door. f The advance edge ofthe hook seat 11 is also preferably provided with a transverse coirugation 23, thereby providing in effect a knob 24 at the advance point of this member. lThe lowermost limit of this knob 24 preferably coincides with or at least does not fall bel/ow the general contour line of the seat of the member 11, an extension of this contour being indicated fr reference purposes by the dotted line 25 in the drawings.

These corrugations and knobs forma positive preliminary supporting arrangement whereby the' door lmay be supported .upon the point of the hook, in a preliminary position, not fully closed. It will be noted that 1n this preliminary position, the 'knob' 24 will fall within the corrugation 19 and the knob 20 will fall within the corrugation' 23. The contours of these corrugations and knobs should be so arranged that the member 11 will not slip oflzctbefpoint of the hook when in such preliminary engagement.

After being supported in this preliminary manner,'the hook may be driven into more complete engagement with the door member 11, this movement of the hook effecting, as heretofore described, the more complete closing `of the door desired.

. Near the junction of the supporting ledge Laaaiaa of the hook with the shank portion of the hook 'there may be formed a knob/26, which should'eirtend above the general contour of the ledge, the extension of this contour being indicated, as before stated, by the dotted line 25.

' As the hook is driven beneath -the door member 11, the knob 26 will, when the hook is in almost complete engagement with the door, contact the knob 24. Further driving of the hook will produce an exaggerated lifting motion of the door by causing the knob 26 to ride over the knob 24. When the hook has been driven into complete and final position the knob 26 will fall within the corrugation 23 and the knobv24 will be in osition beyond the knob 26, thereby positively interlocking the two parts in such manner that, it will be necessary to drive the hook from beneath the door. Accordingly, by no chance willl the hook become disengaged from the door by accident.

The contours of the knobs and corruga-l tions just described may be so arranged that when the hook is in final position beneath the member 11, the support will be upon the mainportion of the contour of the ledge of the hook and not upon any of the knobs or corrugations, it being the principal function of these knobs to serve as preliminary supporting means and as final interlocking means rather than as final supporting surfaces, although in some embodiments it may be desired to utilize these members forinal supporting as wellas for the other purposes described. i i' The back of each hook-is preferably provided with a suitable surface 27 against which blows may be directed to 'force thel hook beneath the door arm. The surface ioo 27 is so designed and located that impact from these blows will produce the desired results in a suitable manner without injury ,to the hook or interference with the functioning of the device. The bracket constituting this striking face 27 is also arranged to extend outwardly from the main ortion of the hook so that it may be struc 'by a suitable instrument for driving aving thus described my invention, what I claim is: v

1. ln a door mechanism for railway cars,

tending to assist the opening the hookI l out of engagement with the door.' The ef lclined in such manner that the door will be forcibly closed by the action of the hook when the said hook is moved from a preliminary to a final engaging position.

'2. ln a door mechanlsm for railway cars, the combination with a swinging door having a hook seat formed thereupon Iof a hook pvoted upon the car body and adapted to supportingly engage the said door seat, the

said hook being provided with a supporting ledge, the point thereof lying at a greater distance from the pivot point of the hook than the root of the said ledge, the said hook seat being so formed that when the ledge of the said hook is in partial engagement therewith the door will be held in a partlyl closed position, and that when the said ledge is in complete engagement therewith the door will be held in a fully closed position, the said ledge and the said door Seat be formed to cause lifting of the door when the hook is moved frompartial to complete engagement with the said door seat.

3. lin a door arrangement for railway cars, the combination with ya swinging door having .a hook-engaging seat formed thereupon of a door-supporting hook pivoted upon the car body, the door-engagingl ledge of the said hook being provided with a lnobbed point adapted tov engage a cooperatively formed surface on .the forward edge oi the said door seat to support the door in a partly closed position,` other portions of the said ledge and seat being cooperatively formed in suchmanner that movement of the hook into further engagement with the door will eiiect further closing of the door.

4. ln a door arrangement for railwaycars, the combination witha swinging door having a hook-engaginglseat formed thereupon of a door-supporting hook pivoted upon the car body, the door-supporting ledge of the said hook being formed along an inclinedv path, eccentric to the axis of swing of the hook, and the door seat being formed along a path conforming substantially thereto, the

forward edges of the hook ledge and the seat being provided with interengaging shouldered portions adapted to support the door in a partly closed position, said shoulders lying within the limits of the normal contoui` lines of the respective members.

5. in a door arrangement for railway cars, the combinationl with a swinging door having a hook-engaging seat formed thereupon of a door-supporting hook pivoted upon the car body, the door-supportlng ledge of the said hook being formed along an inclined path eccentric to the axis of swing/of the hook, andl interlocking shoulders formed upon the hook ledge and the door seat, the same being arranged to assume interengag-v ing positionl when the hook'is in full engagement with the door seat,` and bein adapted to resist retraction of the hook from position beneath the door seat, along the said inclined path.
